IMPROVEM ENT IN PLOW-CLEANERS.

Specification forming part of Letters Patent No. 56,296, dated July 10,1866.

To all whom it may concern:

Be it known that I, OSCAR F. WARREN, of the town of Pembroke, county ofGenesee, and State of New York, have invented a new and improved devicefor clearing plows of such clogging matter as collects under theplowbeam when plowing stubble-ground and the like; and I do herebydeclare that thefollowing is a full and exact description thereof,reference being made to the accompanying drawin g and the letters ofreference thereon, making a part of this specification.

V The nature of my invention relates to the arrangement of a series ofthree levers with a plow in such manner that the operating-lever isconnected to the land-side plow-handle by a fulcrum-bolt, and theclearing-lever connected to the plow-beam bya fulcrum-bolt, and these,with the connecting-lever, made adjustable, so that the clearing-levermay be made to act in front of the colter, when a colter is used on theplow, or in front of the standard which connects the plow to the beam,when a colter is not used, and so that the operating lever will alsoserve as a handle to hold and guide the plow.

To enable others skilled in the art to make and use my invention, 1 willfully describe its construction and operation.

Having reference to the drawing, A represents the plow-beam; B, theplow-point; G, the iron standard, which connects the landside D and moldboard E to the plow-beam.

H is a screw-nut, which secures the standard to the beam. I and l arethe handles by which the plow is held and guided. All of these parts areand may be of common construction and admit of the application of myinvention.

The levers and their arrangement, which comprise my invention, arerepresented at O Gr F. The operating-lever O is connected to theland-side plow-haudleby means of a fulcrum-bolt, as shown at a, the saidlever projectin g upwardly and forming ahandle within easy andconvenient grasp of the plowman. This lever being so connected to theplow-handle, and projecting upwardly and within easy grasp of theplowman, the plow can be guided nearly as well when the plowman has holdof this lever as when he has hold of the plow. handle, and hence theclearing-lever may be operated by the plowman without inconvenience andwithout endangering the proper holding and guiding of the plow.

The clearing-lever F is connected to the plow-beam by a fulcrum-bolt, asshown at b,

at such point as to place it'in front of the colter, when a colter isused; or it may be placed farther back, so as to act directly in frontof and in proximity to the standard, as shown in the drawing, and thusbe made to clear away the clogging matter which is liable to collectunder the beam in front of the colter, or the clogging matter which isliable to collect under the beam at the connection of the standardtherewith.

The lever which forms the connection between the operating-lever and theclearing-lever is shown at G. All of these levers have adjusting-holese, by which they may be adjusted and accommodated to the plow, eitherwith or without a colter, and also accommodated to the peculiarcondition of the ground to be plowed.

When the construction of the plow is such as to set the standard 0 atthe center of the plow-beam, then the lever F may be bent a little underthe beam, in order to allow the end of the lever to work in contact withthe standard; but when the standard is set flush with the outside of theplow-beam, then such bend in the lever is not required.

It is evident from this arrangement of the levers that the plowman caneasily, by a backand-fortll movement of the operating-lever, thrust theclearing-lever against any clogging matter-such as stubble, grass,weeds, vines, and the like-which may collect under the plow-beam whenplowing, and clear it away, and thereby prevent such clogging matterfrom obstructing the plow.

It isalso evident that the plowman may operate these levers for thepurpose designed, and at the same time hold and guide the plow withoutdifficulty.

Having now described my invention, what I claim therein as new, anddesire to secure by Letters Patent, is-

1. The adjustable levers O Gr F, so connected and arranged that theclearing-lever said operating-lever will also serve as a handle may beoperated either in front of a eolter or to guide and hold the plowsubstantially as in front of the plow-standard, for the purpose setforth.

and substantially as set forth. OSCAR F. WARREN.

2. Connecting the operating-lever O to the Witnesses:
